Open Core IP time limited source files expired.

hi, after using Quartus II 7.0 full version and the NIOS 2 open core plus for a week. I could not synthesize my NIOS 2 system since the cpu.v is a time-limited files. do you guys have this problem? ...

I was just following one of the tutorials on building system using SOPC builder. When I tried using the programmer it said that the file had a few IP core services which uses hardware evaluation and hence I could not program it into the FPGA.

I am using DE2 kit from Altera and I have not purchased a license.

As soon as I click on the programmer, a dialog box pops up which tells me that the file is time limited.

You are probably misunderstanding the meaning of the warning messages. The programmer can configure the FPGA with a time-limited SOF.

You should see two warning messages. One is from the assembler. It is telling that it can't generate device programming files. This means it can generate a SOF for configuring the FPGA, but it can't generate a POF for programming a flash device.

The second warning is from the programmer when configuring the FPGA. The warning is telling you that it is a time-limited SOF. This means that the evaluations cores require a permanent link with Quartus programmer, or they would stop working after a certain time.
